Why isn't there an offline feature?

POE 2 deserves an offline feature/mode. Not everyone wants their guild/friends to know they are online, they just want to enjoy the game. We get it....it's a multiplayer game... but /dnd does not assist every player the way we wish to enjoy the game. It should be a simple feature that you can turn on and off for private gamepley versus multiplayer gameplay... why isn't this an option?
